Covalent organic framework-modified poly acrylic acid binder enhances cycling performance of silicon-carbon anodes

Key Points

• This research aims to improve the cycling performance of silicon-carbon anodes in lithium-ion batteries using a modified binder.
• Developed a novel binder, PAA@Tp-DCAP-COF, for silicon-carbon composite anodes.
• Conducted cycling tests to evaluate performance improvements.
• Analyzed structural integrity during battery operation.
• The modified binder significantly reduced volume fluctuations during cycling.
• Cycling performance of the silicon-carbon anodes showed considerable enhancement compared to traditional binders.
• Structural degradation was minimized, leading to improved longevity.
